Just did my first clean install w/ 1903, no more bloat in the Start Menu! Sweet Jesus, Microsoft did something right!
I didn’t check before joining the laptop to our domain but after logging in with a new domain user account there were only 2 tiles pinned by default: Office (advertisement) and Edge (sigh.) Looking through the Start Menu there were no shortcuts in the app list either for Candy Crush or the rest of that crap. The only thing I don’t like is the narrow Start Menu layout it defaults to, it looks terrible on a 1366 x 768 laptop screen, same with the taller OneDrive right-click menu which only provides the benefit of the Settings link not being covered by the advertisement pop-up that appears on first click.
